SHINGLE ELEMENT.

Application filed October 2, 1924. Serial N0. 741,116.

This invention relates to improvements in shingle elements, and refersmore particularly to individual self-spacing shingle strip slabsmanufactured from a sheet of roofing material without any waste incutting, to produce a roof presenting octagonal areas of a predeterminedcolor, with contrasting areas of dili'erent configuration of differentlongitudinally.

colors.

Briefly, a sheet of previously prepared roofing material having agranular surfacing on one or both sides, is fed to a roofing machine andcompletely severed into individual shingle strips either transversely orIn the preferred form of operation, it is severed transversely.-Intermediate the severed edges the body of the sheet are produced aplurality of spaced apart semi-octagonal incisions. These incisions maybe produced directly on the severed edge or may be made within the bodyof the. sheet not communicating with said severed edge. The portionsbetween these incisions may be then folded overthe main body portion ofthe sheet, and in combination with other strips of the same design, whenassembled to form a roof covering will present a series of parallel orstaggered oetagonalareas of predetermined color with areas of differentconfigurations of contrasting color.

The arrangement of design is such that there is no waste or loss ofmaterial in cutting the strips from a continuous sheet, while at thesame time, the strips produced in accordance with. this invention areself-spacing relative to each other. The economy of construction, theease of assembly on a roof, the sturdy character of the assembled roofstructure and the attractive beauty of the roof are a few of the manyadvantages immediately apparent to those skilled in the art.

In the drawings:

Fig. 6 is a diagrammatic plan view of a modified shingle strip. Fig. 7is a plan view of the construction shown in Fig. (3, showing the mannerof folding.

Referring in detail to the dra ings, 1 designates a shingle strip,substantially rectangular in shape and of greater width than length.This strip has been severed from a continuous sheet of roofing felt,saturated with a waterproofing composition such as asphalt, andpreferably having one surface only covered with granular material of apredetermined color, such as gray, red, slate, green, etc. The sheet maybe severed transversely along the line 2 or longitudinally along theline 3 to produce the shingle strip 1, shown in Fig. 1. In the preferredform of strip, shown in Figs. 1 to 5, there are produced a plurality ofspaced apart semioctagonal incisions 4, the base of which is spaced ashort distance from the edge 2. The exposed body portion of the stripmay have imposed thereon a granular surfacing 5 while the opposite sidemay be devoid of granular material and present the color of thewaterproofing material, for instance, black.

The lower portion of the strip is then folded along the unbrokenconnecting portions between the incisions and attached to the bodyportion of the strip, thus producing a series of uniformly spacedoctagonal areas 6, of a predetermined color constituting the exposedlower edge of the strip. These hexagonal areas 6 contrast verystrikingly with the black surface areas 7 of the portion folded over.The upper edge 8 of this latter folded portion will produce a shoulderagainst which the lower edges of overlying shingles will abut. Thislatter self-spacing feature, of course, is dependent on whether or notthe entire area of the folded ortion is completely attached to the mainb0 y portion. a

. It must be understood that the up er portion of the folded piece maybe eft unattached to form pockets into which the lower edges ofoverlying shingles may be inserted and securely interlocked. 4

lVhen assembled on a roof, the hexagonal areas 6 may be staggeredrelative to each other in a. vertical plane (Fig- 4), or they may bearranged in parallel, as shown in Fig. 5. As one illustration of thecolor combinationwhich may be used, the hexagonal areas may be coveredmaterial. Thus, in an assembly on a roof, there will be a strikingcontrast between the red hexagonal areas, the black areas ofthe foldedportion and the shaded areas between the two. It must be understood,'of

course, that any colors may be used and that tion may be attached to thebody portion to provide a shoulder for self-spacmg overlying strips, ora portion left unattached to produce a pocket, into which overlyingshingles are inserted, and with whichthey are interlocked, as heretoforepointed out. When assembled on a roof, the hexagonal areas may bestaggered or parallel relative each other.

I claim as my invention:

1. As a new article of manufacture, a roofing strip having a bodyportion, two sides and an upper edge, a base provided with spacednotches and interposed tabs between the notches and an integraloverlying strip attached to the body portion, the strip having thecharacteristics of having been formed by first making spaced angledincisions adjacent the lower edge of the strip, and then folding saidlower edge on the lines of the incisions back upon the body portion ofthe strip;

2. As a new article of manufacture, a roofing strip of flexible materialhaving a.

with red granular edge provided body portion, two sides and an upperedge, a base provided with spaced notches and tabs between the notchesand an integral overlying strip attached to the upper sur-t face of hebody portion, the overlying strip roofing strip of flexible materialhaving granular material imposed on one surface,

having a body portion, two straight sides and an upper straight edge,the lower edge provided with spaced notches and tabs be tween thenotches, and an integral overlying strip attached to the upper surfaceof the body portion, the overlying strip having the characteristics ofhavingbeen formed by first makingspaced angled incisions adjacent thelower edge of the strip and then folding said lower edge along the linesof the incisions back upon the body portion of the strip.

4. As a new article of manufacture, a roofing strip having a bodyportion, straight sides and a straight upper edge, the lower with spacedtabs of semioctagonal configuration and notches between the tabs and anintegral overlying stri attached to the body portion, the over yingstrip having the characteristics of havm been formed by first makingspaced angle incisions adjacent the original lower edge of the strip,and then folding said lower ed e along the lines of the incisions uponthe ho y portion areas adjacent the then lower edge of the strip.
